The Factor programming language is a concatenative, stack-based programming language with high-level features including dynamic types, extensible syntax, macros, and garbage collection. On a practical side, Factor has a full-featured library, supports many different platforms, and has been extensively documented.

John Benediktsson & Doug Coleman give a tour of the language and when has been added in recent years.

This keynote talk is titled "Software Doldrums," as presented by Rek and Devine of Hundred Rabbits.

Hundred Rabbits is a small artist collective consisting of Rek, a writer and cartoonist, and Devine, a programmer, artist, and musician. They travel the globe together with their sailboat named "Pino" while creating and adapting, among other things, software to fit their needs.

Part of their software stack is UXN, a VM and programming language influenced by Forth.

This talk, which was featured as a keynote at LibrePlanet 2022, is about the dangers and shortcomings of relying on always-online proprietary platforms. Hundred Rabbits will share how they reimagined their software to encourage the reuse, repair and maintenance of existing hardware.

Ulli Hoffman did a great tutorial on "Defining Forth Data Structures / Records" last weekend, a video recording is available at <https://youtu.be/6xFYcHhjojY?t=102>.

In der letzten VD hatten wir mit SectorForth ein Beispiel für Forth-Minimalismus. Das SectorForth passt in die 512 Bytes des Bootsektors einer Diskette oder Festplatte eines PC Systems. PlankkForth ist nun ein weiteres Beispiel für Forth-Minimalismus:

PlackForth ist ein Linux-Programm als handgeschriebene ELF-Linux-Datei (ELF = Executable and Linking Format - Dateiformat für ausführbare Dateien unter Unix/Linux). D.h PlankForth liegt nicht im Quelltext als Assembler oder Hochsprache vor, sondern wurde vom Autor Koichi Nakamura manuell in einer Hex-Datei geschrieben. Diese Hexdatei ist der "Quellcode" und wird in Binärcode "übersetzt".

Das Ergebnis ist ein minimales Forth mit 37 Forth-"Wörtern" die jeweils aus nur einem Buchstaben (bei Unterscheidung von Gross- und Kleinschreibung) bestehen. Das resultierende Binärprogramm ist genau 1024 Bytes gross, also doppelt so gross wie SectorForth.

Ben Hoyt made a benchmark test in various languages, and compares performance across them.

The discussion in c.l.f. about the optimisations of the Forth version are an interesting read

Anton Ertl is working on a new Forth system written in amd64 assembly. The main goal of fforth is to demonstrate modern Forth implementation techniques, in particular: header structures that directly represent, e.g., compilation semantics and recognizers

It is work in progress and can be found on Github: https://github.com/AntonErtl/fforth

A nice example on how to bootstrap a forth system from a bare minimal binary:

Collapse OS is an attempt to implement a simple OS that can run on anything computer-ish in case civilisation collapses

Originally in assembler, the people around it discovered and then adopted Forth

The discussion around this topic is interesting

Philip Zembrod has published a C-Compiler written in Forth that targets the 6502 CPU called cc64.

cc64 produces faster code than cc65 and Power C
